DETAILED DESCRIPTION
[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments. Example 1
[0020] A water conservancy project gate with barnacle cleaning function, such as Figure 1 and Figure 4 As shown, it includes a first support frame 1, a gate plate 2, a scraper 3, a second support frame 4, a motor 5, a rope 6 and a pulley 7. The second support frame 4 is installed on the top of the first support frame 1. The first support frame is in the shape of a door frame, and inclined support columns are symmetrically distributed on both sides for support. The main body of the second support frame 4 is two vertical rods, which are symmetrically installed at the two ends of the top of the first support frame, and a number of rods for fixing are distributed between the two vertical rods and on the sides. Pulleys 7 are installed at the upper and lower ends of the two vertical rods of the second support frame 4. Ropes are arranged on the pulley sleeves at the upper and lower ends of the vertical rods. Motors 5 are installed on both sides of the top of the frame 1, and the position of the motor 5 corresponds to the position of the pulley 7 at the bottom of the vertical rod in the second support frame 4. The output shaft of the motor 5 is connected to a disc, and one end of the rope 6 is sleeved on the disc of the output shaft of the motor 5. The first support frame 1 is movably installed with a gate plate 2 through the rope 6 sleeved on the pulley 7. A scraper 3 is slidably installed on the first support frame 1, and the scraper 3 is close to the surface of the gate plate 2. The scraper 3 is serrated. The scraper 3 is positioned with the gate plate 2 through a positioning device. The scraper 3 collects the scraped material through a collecting device and cleans itself through a cleaning device.
[0021] like Figure 3 As shown, the positioning device includes a first wedge block 15, a second wedge block 16 and an elastic member 17. A plurality of first wedge blocks 15 are equidistantly installed on both sides of the gate plate 2 in the vertical direction, and second wedge blocks 16 are installed on both sides of the scraper 3. The first wedge block 15 and the second wedge block 16 are both prism-shaped, and the inclined surfaces can be squeezed against each other. Both ends of the scraper 3 are slidably installed on the first support frame 1, and both ends of the scraper 3 are sleeved with elastic members 17. The elastic member 17 can be a spring or rubber with elastic properties. As a preferred embodiment, the elastic member 17 is a compression spring.
[0022] like Figure 2As shown, the cleaning device includes a high-pressure nozzle 8, a first explosion-proof pipe 9, a high-pressure water pump 10, a second explosion-proof pipe 11 and a fixing buckle 18. A high-pressure water pump 10 is installed on one side of the top of the first support frame 1, the water suction end of the water pump is connected to the second explosion-proof pipe 11, and the water outlet end is connected to the first explosion-proof pipe 9. The first explosion-proof pipe 9 and the second explosion-proof pipe 11 can effectively prevent the occurrence of pipe bursting. A plurality of fixing buckles 18 are equidistantly installed on the top of the first support frame 1. The fixing buckles 18 are hook-shaped. The first explosion-proof pipe 9 is fixed to the first support frame 1 through the fixing buckles 18. Fixing the first explosion-proof pipe 9 can effectively prevent the first explosion-proof pipe 9 from being thrown off due to high water pressure. High-pressure nozzles 8 are equidistantly installed on the first explosion-proof pipe 9. The position of the high-pressure nozzle 8 corresponds to the position of the scraper 3, and the water spraying end of the high-pressure nozzle 8 is facing the scraper 3.
[0023] like Figure 2 As shown, the collecting device includes a collecting frame 13 and a filter net 14. The collecting frame 13 is movably installed at the bottom of the first supporting frame 1. The collecting frame 13 is a rectangular frame. The bottom of the collecting frame 13 is open. The filter net 14 is installed at the bottom opening. The filter net 14 can allow water to pass through, while barnacles will remain on the filter net 14.
[0024] like Figure 2 As shown, it also includes a baffle 19 and a torsion spring 20. The baffle 19 is tiltedly installed on the first support frame 1 through the torsion spring 20. The upper end of the baffle 19 is far away from the gate plate, and the lower end is close to the gate plate. The torsion spring 20 is installed on both sides of the upper end of the baffle. One end of the torsion spring 20 is fixedly connected to the first support frame 1, and the other end is fixedly connected to the baffle 19.
[0025] like Figure 2 As shown, a counterweight frame 12 is also included. The end of the second explosion-proof pipe 11 away from the high-pressure water pump 10 is fixedly connected to the counterweight frame 12. The counterweight frame 12 is hollow inside and has a plurality of through holes on the side. The second explosion-proof pipe is inserted into the hollow part of the configuration frame 12.
[0026] Every time the gate plate 2 needs to be opened, the motors 5 on both sides of the top of the first fixed frame are started first. The motors 5 will drive the disc on its output shaft to rotate. At this time, the ropes 6 will slowly move along the pulleys 7 on the second fixed frame so that the ropes 6 are sleeved on the disc. The movement of the ropes 6 will drive the gate plate 2 to rise, and the scraper 3 will begin to scrape the barnacles on the two surfaces of the gate plate 2. When the scraper 3 is about to deviate from the gate plate 2, the second wedge blocks 16 equidistantly distributed on both sides of the gate plate 2 will squeeze the first wedge blocks 15 installed on both sides of the scraper 3 one by one to ensure that the scraper 3 does not deviate from the gate plate 2. The elastic members 17 sleeved on both sides of the scraper 3 also have a certain stabilizing effect on the deviation of the scraper 3. The scraped barnacles will fall on the filter screen 14 of the collection frame 13, and the filter screen 14 will only filter out water. When the scraped barnacles are large in size, the barnacles will first fall on the baffle 19 because the baffle The lower end of 19 is installed with an inward tilt, so the barnacles will fall into the collecting frame 13 along the tilted baffle 19. If the length of the barnacles is longer than the distance between the lower end of the baffle 19 and the gate plate 2, the lower end of the baffle 19 will be squeezed by the barnacles, and the torsion spring 20 at the upper end of the baffle 19 will be twisted. Then the baffle 19 rotates. At this time, the distance between the lower end of the baffle 19 and the gate plate 2 becomes larger, and the barnacles can fall smoothly into the collecting frame 13. When the scraper 3 needs to be cleaned, start the high-pressure water pump 10, and the high-pressure water pump 10 will absorb water through the second explosion-proof pipe 11, and then transport the water to the first explosion-proof pipe 9, and spray the water onto the scraper 3 through the high-pressure nozzle 8, so as to clean the scraper 3. The counterweight frame 12 fixed at one end of the second explosion-proof pipe 11 on the high-pressure water pump 10 is to keep the water suction end of the second explosion-proof pipe 11 in contact with water at all times, so as to ensure that the high-pressure water pump 10 can absorb water.
[0027] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
